AWS Managed Services is excited to announce support for 29 new AWS services. With this release, the total number of services supported by AMS is almost doubled to 61, including AWS Lambda, a much requested service. In addition to running these services within secure and operated AMS managed accounts, several can be self provisioned and configured directly in the AWS Console or the APIs. With this release, AMS is also introducing a second pricing tier that is lower for certain groups of AWS services where more of the day-to-day operations is handled by the service itself. Contact your sales representative for more details on AMS pricing.
